System and method for facilitating electronic financial transactions during a communication session

ABSTRACT

A payment button on a device capable of making telephone calls, such as a mobile phone, allows a payer to electronically transfer money while in a phone call with a payee. The payment button also allows a payee to initiate an electronic payment transaction while in a phone call with a payer. The payment button may be a clickable or tappable virtual button presented on a display of the phone when being used to make or receive a call. The payer or the payee can simply enter a payment amount on the phone to complete an electronic payment transaction. A notification of payment is instantly transmitted to the phones being used for the phone call, so that the parties can safely and conveniently conclude a purchase and/or payment transaction during one phone call.

BACKGROUND Technical Field

The present invention generally relates to facilitating electronic commerce over a network and, more particularly, for facilitating the use of smart telephones in financial transactions.

Related Art

Consumers and the general population own and use mobile phones with enhanced capabilities, also known as smart phones, more than ever before. The number of users, devices, and device capabilities continue to increase. One of the reasons for this increase is the capability of these phones to expand the mode of communication beyond simple voice conversation. Developers can provide smart phone applications (“apps”) that augment voice communication in various ways. For example, apps can allow users to make video calls, share photos and videos, play games together, and carry out electronic transactions with each other, such as sending and receiving money.

At the same time, more and more people rely on payment service providers, such as PayPal, Inc. of San Jose, CA, to send and receive payments. Such payment service providers can make transactions easier and safer for the parties involved. For online purchases, online merchants typically provide a checkout link or button for accessing a payment service provider from the merchants' webpage, making it convenient for consumers to complete online purchases through payment service providers. The convenience provided through such integration is one main reason why online purchases and use of payment service providers have become popular.

However, a large number of purchase orders are still placed over a telephone conversation. For example, orders for food delivery are typically made verbally over a phone call. Promises to buy and sell between ordinary non-merchant parties are typically made verbally over a phone call also, since non-merchant sellers are not likely to have an online checkout page. In fact, some consumers may actually prefer to make a purchase agreement over a phone conversation, since questions they may have about the purchase can be asked and answered in real time to facilitate a purchasing decision.

Even though these over-the-phone transactions would benefit greatly from the safety and convenience provided by payment service providers, and even though many people own smart phones that are capable of accessing payment service providers, over-the-phone transaction typically are not completed through payment service providers. One of the main reasons is that unlike online merchant websites, the lack of integration makes it cumbersome for users to access payment service providers during a phone call.

Thus, there is a need for integrated access to payment service providers to facilitate electronic payment transactions during a phone call.

SUMMARY

According to one embodiment, a button or link is provided on a display of a user's mobile phone during a phone call with another party, where the user may select the button or link to make a payment request to or from that party during the call. The button may be provided through an app or service from a payment provider, where the payment request to or from the user is processed through the payment provider.

According to one embodiment, an in-call payment application on a payer's mobile phone presents a custom in-call screen having a clickable or tappable payment button on the display of the mobile phone when the payer calls a payee or receives a call from a payee. After the payer and the payee verbally agree on the purchase price, the payer may tap or click on the payment button to activate a payment handler module. The payment handler prompts the payer to enter the payment amount and the user identifier (“ID”) of the payee. If the user ID of the payee, e.g., the payee's email address, is stored in the address book of the payer's mobile phone, the application retrieves it so that the payee's user ID is automatically entered in the payment handler prompt. Once all the information is entered, a payment request, which comprises the payment amount and the payee's user ID, is transmitted to a payment service provider over a data network. The payment service provider processes the payment request, and then sends a notification to the payee once the payment request has been processed. The notification may be sent via Short Message Service (“SMS”) text, email, and/or voice alert. If the payee's device is also a mobile phone running an in-call payment application, the notification may be received by the application so that the notification may be presented on the display of the payee's device.

In another embodiment, the payee may trigger the payment handler on the payer's device. In one embodiment, the payee device is also a mobile phone running an in-call payment application. The payee can click or tap the payment button to activate a payment handler, then choose a request payment option in the payment handler to enter the requested amount. Once the requested amount is entered, the payee's device can send an activation command, along with the requested amount and the payee's user ID, to the payment handler on the payer's device via in-band signaling, such as Dual-Tone Multi-Frequency (“DTMF”) signaling, over a voice call network. Internet protocol (“IP”) over a data network may also be used to transmit the command, in which case the user ID of the payer is entered by the payee or automatically retrieved by the application if it is stored in an address book of the payer device. In response to the activation command, the payment handler on the payer's device displays the payment request information and prompts the payer for approval. If the payer approves, the payment request is sent to a payment service provider for processing and notification.

In another embodiment, the payee's device may be a landline phone. The landline phone may be enhanced with capabilities to display prompts and allow the payee to enter a requested amount and user IDs, as well as to communicate via in-band signaling over voice channels and/or IP. In yet another embodiment, an add-in module to a conventional landline phone may have these capabilities. In either embodiment, the landline phone can be used in place of a smart phone to trigger the payment handler on the payer's device.

By providing a payment button on the in-call screen and/or on the phone, the payer can conveniently access a payment service provider to complete a transaction while still on the phone. Also, by instantly notifying the payee, the payee can be assured that a payment has been received even before ending the phone call. Moreover, since user IDs may be automatically retrieved from address books, all that the payer or the payee needs to do may be simply tap on a button and enter a payment amount in order to safely complete a payment transaction while on the phone.

These and other features and advantages of the present invention will be more readily apparent from the detailed description of the embodiments set forth below taken in conjunction with the accompanying drawings.

Embodiments of the present disclosure and their advantages are best understood by referring to the detailed description that follows. It should be appreciated that like reference numerals are used to identify like elements illustrated in one or more of the figures, wherein showings therein are for purposes of illustrating embodiments of the present disclosure and not for purposes of limiting the same.

DETAILED DESCRIPTION

FIG. 1 is a flowchart 100 illustrating steps in which a payer-initiated electronic payment transaction during a phone call is handled according to one embodiment. The payer may be engaged in a phone call conversation using a user device, which can be a smart mobile phone, a landline phone with a processor, a tablet device, or any other computing device that can also be used to make a telephone call. A user device used by a payer may also be referred to as a payer device in the present disclosure. At step 102, the payer may call to a payee or receive a call from a payee on the payer device. The payer and the payee may then verbally negotiate purchasing and/or payment agreement over the call, which is how a large number of purchasing and/or payment agreements and negotiations are still made these days. For example, orders for food delivery are typically made verbally over a phone call. Purchase and/or payment agreements between non-merchants may also be typically made verbally over a phone call, since the parties may prefer that questions about the purchase and/or payment be asked and answered in real time to facilitate a decision to buy or sell.

At step 104, the payer and the payee may verbally agree on an amount pay to the payer. The payee may verbally convey the requested amount, to which the payer simply agrees, or the parties may verbally communicate their intention to be bound to a payment amount in any other suitable way.

After the parties agree on the payment amount, the payer can tap, click, or push a payment button on the payer device to activate a payment handler during the phone call in step 106. Note that step 104 may be omitted, and the payer may simply select the payment button to initiate a payment without any verbal agreement during the call. In this embodiment, the payment button may be a soft key or button presented on a display of the payer device such as a smart mobile phone. For example, an application (more commonly called “app”) on a smart mobile phone can provide a custom dial pad and in-call screen that the payer and the payee can use when making or receiving calls. Such an app may be referred to as in-call payment app in the present disclosure. The in-call payment app can provide a soft payment button on the dial pad or in-call screen when the parties are engaged in a phone call. The soft payment button may be clickable with a pointing device, and may also be tappable if the display is touch-sensitive. Alternatively, the in-call payment app may assign one or more programmable physical buttons to function as the payment button. In other embodiments, the payment button may be a physical button that is programmed or hardwired to activate the payment handler. In any case, these embodiments are meant to be merely exemplary, and one of skill in the art will recognize that there may be a variety of other means, within the scope of present disclosure, for receiving a user's command to activate, invoke, or trigger a software or hardware procedure while the device is being used for a phone call. One such means may be a voice command.

In various embodiments, the payment handler may be a software module, process, subroutine, or function that causes a processor of the payer device to receive information about a payment to be made, such as the payment amount and the user identifier (“ID”) of the payee, and generate a payment request to be transmitted to and processed by a payment service provider (“PSP”) such as PayPal, Inc. of San Jose, CA. For example, PayPal Mobile Payments Library from PayPal, Inc., which is a collection of software modules and corresponding application programming interface (“API”) for allowing users to send and request money via PayPal from smart phones, may serve as a basis for a payment handler. In some embodiments, the payment handler may be implemented in hardware to perform similar functions.

Once the payer activates, invokes, or triggers the payment handler by tapping on the payment button or by other means, the in-call payment app may search an address book stored in the payer device to retrieve the user ID of the payee (e.g., the payee's email address) based on the dialed number or the incoming number, at step 108. If the user ID can be retrieved, the in-call payment app may then transmit the user ID to the payment handler for use in generating the payment request. Thus, the payer can conveniently send payments without having to type in the payee's user ID. If the user ID cannot be retrieved from the address book, the in-call payment app or the payment handler prompts the payer to enter the user ID of the payee at step 110, and saves the user ID for later use in the address book at step 112.

In some embodiments, the payee's phone number may also serve as an alternate user ID. In those embodiments, steps 110 through 112 may be skipped since the payee's phone number obtained from the dialed or incoming number can be used to generate a payment request. When the payment request based on the payee's phone number fails to be processed by the PSP, for example because the payee has not registered his or her phone number with the PSP, steps 110 through 112 may need to be performed on the second try.

At step 114, after the payee's user ID is received, the payment handler prompts the payer to enter the payment amount, such as by entering into a field using a keyboard or keypad or by voice. The payment handler then generates a payment request based on the payment amount and the payee's user ID. At step 116, the generated payment request is transmitted from the payer device over a network to the PSP for payment processing, such as through an API call. In this embodiment, the payment handler may transmit the payment request via application layer protocol such as HTTP or Simple Object Access Protocol (“SOAP”) implemented on top of the Internet Protocol (“IP”). However, one of skill in the art will appreciate that any other suitable protocol for sending and receiving structured data over a network may be utilized without departing from the scope of the present disclosure.

Note also that the payer's user ID and credentials (e.g., password or PIN) may also be required for payment processing by the PSP. However, there is no need for the payer to enter user ID and password every time a payment is made via the in-call payment app, since the information can be entered once and stored in the app when the app is first installed on the payer device. Optionally, for added security, the payment handler or the in-call payment app may perform a step of asking for a password every time a payment request is transmitted. In some embodiments, a unique identifier of the payer's device registered with the PSP (e.g., hardware ID or phone number) can serve as an alternate to the user ID and password, and can be transmitted in place of, or in addition to, the payer's user ID and/or password.

Referring now to FIG. 3 , which is an exemplary flowchart 300 illustrating steps a payment service provider performs in handling an electronic payment transaction initiated during a phone call, the payment request transmitted from the payer device in step 116 above is received by the PSP in step 302. At step 304, the payment request is processed, for example, by verifying the account information of the payer and the payee, adding funds to the payer's account from authorized funding sources, debiting the payer's account, and crediting the payee's account accordingly.

Once the payment is processed, a notification may be sent to the payee. At step 306, the account information of the payee may be checked first to see if the payee has registered with the PSP a user device running a payment handler, mobile payment app (e.g., PayPal Mobile app), an in-call payment app, or other similar software or hardware process capable of communicating directly with the PSP. A user device may be registered with the PSP when such an app is first run on the device. The process of registering a user device with a server is known in the art and thus will not be discussed herein.

If a registered user device is found in the payee's account information, the PSP may directly communicate the notification over a network to the payee's user device in step 308, so that the payee's device can present the notification through a pop-up message, a sound alert, or any combination of these and other suitable means for conveying the notification while the payee is still using the device in a phone call with the payer. If supported by the device, the notification may also be sent to the device via push notification mechanism such as the one described in Bell et al., US 2010/0227632, incorporated by reference in its entirety.

At step 310, the notification may be sent to the payee utilizing other means of communicating a message to the payee regardless of whether the payee has a device running an app registered with the PSP. For example, a Short Message Service (“SMS”) text may be sent so that the payee can receive the notification on the mobile phone being used in the phone call with the payer. An email may also be sent to the payee for notification. In another example, an automated voice response may be injected into the audio stream of the phone call so that the payee can hear a voice notification while on the phone. The PSP may also call the payee on the phone to deliver the automated voice response, which the payee can pick up and hear if the payee's phone has a call-waiting enabled. For added security, the notification message in these examples may include a secret message for the payee, as described in the commonly-assigned patent application publication US 2009/0327099 by Patel et al., incorporated by reference in its entirety. Optionally, a notification may also be sent to the payer by performing steps similar to steps 308 and 310 described above.

Referring back to FIG. 1 , at step 118, the payee receives the notification sent by the PSP as described above. The payee can then be assured that the payer made the payment as promised, and verbally acknowledge receipt of the payment while still on the phone with the payer, at step 120. With the assurance that the payment has been received, the payee may initiate transfer of goods or services to the payee. The payer can be assured that the payee, having been paid as promised, would start the delivery of goods or services. Thus, the process described above enables users of PSPs to make purchases and payments safely and conveniently in one integrated transaction over one phone call.

Note that the methods and system in the present disclosure assume that the payer and the payee have accounts with the PSP. If one or both parties do not have an account, one may be created prior to taking advantage of the benefits provided by the methods and system disclosed herein, by supplying information such as a funding account number, a password, a user name, an email address, and a phone number to the PSP. An account may be created, for example, when the payer first installs the in-payment app described above. Account creation is known in the art and will not be discussed further herein.

Referring now to FIG. 2 , a flowchart 200 of steps in which a payee, as opposed to a payer, initiates an electronic payment transaction is illustrated. Both the payer and the payee may be engaged in a phone call conversation using a user device, which can be a smart mobile phone, a landline phone with a processor, a tablet device, or any other computing device that can also be used to make or receive a telephone call. A user device of a payee may also be referred to as a payee device in the present disclosure. At step 202, the payee may call a payer or receive a call from a payer on the payee device, and verbally negotiate a purchasing and/or payment agreement (if desired) over the call as described for step 102 above.

In contrast to the payer activating a payment handler to initiate payment in step 106 above, in step 204, the payee may tap, click, push, or otherwise select a payment request button on the payee device to request payment from the payer. In one embodiment, the payment request button may be provided by the payee device running the in-call payment app described in connection with step 106 above. The payment request button may be presented on the same display as a payment button, or it may be presented after the payee taps, clicks, or pushes the payment button. In another embodiment, the payee device may be a landline phone with a programmable or hardwired button to function as the payment request button. The landline phone may be enhanced with capabilities to display prompts and allow the payee to enter a requested amount after the payee presses the payment request button. In yet another embodiment, an add-in module to a conventional landline phone may provide the payment request button and the input/output capabilities.

After the payee taps, clicks, or pushes the payment request button, the payee device prompts the payee to enter the requested amount at step 206, such as through a keyboard, keypad, drop down menu, voice, or other means. While the information to be transmitted to the payer device includes both the requested amount and the payee's user ID, only the requested amount may need to be entered since the payee's user ID may already be stored in the payee device for reuse. Once the requested amount is entered, at step 208 the payee device can send an activation command, along with the payment information (i.e., the requested amount and the payee's user ID), to the in-call payment app running on the payer's device. The activation command and the payment information may be transmitted via in-band signaling over a voice call channel, for example via Dual-Tone Multi-Frequency (“DTMF”) signaling. Because in-band signaling such as DTMF signaling allows transmission of data and/or command over a voice channel, no connection other than a phone call may be required, allowing even non internet-enabled payee devices, such as a landline phone, to initiate electronic payment transactions. One of skill in the art will recognize that any suitable in-band signaling method other than DTMF signaling may be utilized for practicing the methods and systems disclosed herein without departing from the scope of the present disclosure. For example, as wideband audio or high-definition voice (“HD-voice”) technology currently employed in some telephone networks gains wider acceptance, in-band signaling can be accomplished using high frequency tones (“HF tones”) so that the signaling tones would not interfere with audible voice communication between callers.

The in-call payment app running on the payer device can monitor the phone call between the parties and activate, trigger, or invoke the payment handler on the payer device if an appropriate in-band tone signal is detected. In another embodiment, a payment service provider that is acting as a relay may monitor and detect in-band tone signals such as DTMF signals. In such an embodiment, phone calls dialed on the payer device or the payee device are first connected to a PSP, which then relays the phone call to the dialed number. This allows the PSP relay to monitor the phone call audio stream to detect in-band tone signals. In response to the detected in-band tone signal, the PSP may process a transaction and/or retransmit command and data over the Internet to an IP-enabled payer device. Also, in an embodiment in which the PSP acts as a relay, the PSP may directly inject an automated voice alert or an in-band signal into the phone call audio stream for transmitting a notification described in connection with steps 308 and 310 above.

Optionally, if the payee device is capable, internet protocol (“IP”) over a data network may also be used to transmit the activation command and the payment information in place of, or in addition to, in-band signaling. For example, a smart phone with a mobile data connection or an IP-enabled landline phone being used as a payee device may allow the payee to select IP as the transmission protocol. If IP is selected as the transmission mechanism, the payee device may need to obtain the payer's user ID in order to reach the payer device. The payer's user ID may be obtained and/or stored for reuse by performing steps similar to steps 108 through 112 described above. In some embodiments, the payer's phone number may serve as an alternate to the user ID, and may be used in place of, or in addition to, the payer's user ID.

At step 210, the activation command and the payment information is received by the payer device, and in response the payment handler is activated to display the payment information (e.g., the payee's user ID and the payment amount). The payment handler also prompts the payer to approve the payment. Optionally, the payment handler or the in-call payment app may perform a step of asking for a password for added security when the payer approves. Also, if the payee's user ID received by the payer device is not found in an address book, the payee's user ID may be stored in the address book so that the payee's user ID can be automatically retrieved for subsequent transactions.

If the payer approves the payment at step 212, the payment handler generates a payment request based on the payment amount and the payee's user ID received in the payment handler. The transmission of the payment request to a PSP at step 214, as well as the receipt of a notification by the payee at step 216 and a verbal acknowledgement of the payment to close the transaction at step 218, are the same as steps 116, 118, and 120 described above and will not be repeated here in detail. Processing of the payment request and transmission of a notification are performed using the same steps in FIG. 3 as described above for the payer-initiated transaction.

Therefore, according to one aspect of the present invention, the system and methods disclosed herein enable a payee to simply select a button and enter a requested amount to initiate an electronic payment transaction during a phone call with a payer. The payer can simply respond by approving the requested payment displayed on the payer's device, and the parties can safely close the purchase and/or payment transaction in the same phone call after the payee receives a notification that the payment has been processed.

Further, one of skill in the art will recognize that the requested amount may be obtained from the payee in various ways without departing from the scope of the present disclosure. For example, the in-call payment app running on the payee device may communicate with, and obtain a payment amount directly from, a variety of other apps that may be utilized by the payee. These apps may include a calculator app, an inventory management app, or apps that help merchants manage online sales, such as eBay Mobile app by eBay, Inc. of San Jose, CA. These apps may also be integrated into the in-call payment app. In another example, a landline payee device may be linked to an electronic cash register to obtain a payment amount directly from the register. Thus, in these examples, the payee may not need to enter the requested amount into the payee device manually.

FIGS. 4A to 4C illustrate an exemplary system in which both the payer device and the payee device are mobile phones capable of performing methods for facilitating an electronic payment transaction during a phone call. FIGS. 4A to 4C also show exemplary screen displays with which the payer and the payee may interact while a payer-initiated electronic payment transaction is being carried out.

In FIG. 4A, a payer device 402 and a payee device 422 each comprises a touch-sensitive display 404, 424 and a plurality of programmable buttons 406, 426. The payer device 402 and the payee device 422 are both capable of making and receiving a phone call over a voice call network 490, such as public switching telephone network (“PSTN”), public land mobile network (“PLMN”), cellular network, or any combination of such networks that carry voice communication between mobile devices. The voice call network 490 may also include voice over IP (“VoIP”) on a data network comprising LAN, WLAN, and various other wired and wireless networks. The payer device 402 and the payee device 422 also communicate with a payment service provider (“PSP”) server 470 over a data network 480 comprising LAN, WLAN, and various other wired and wireless networks such as PLMN and cellular network. The PSP server 470 may be operated by a PSP such as, for example, PayPal, Inc. of San Jose, CA.

One of skill in the art will recognize that the payer device 402 and the payee device 422 are smart mobile phones with touch-sensitive displays and a plurality of programmable buttons that enable the functions discussed above with reference to FIGS. 1 and 2 . However, a variety of other computer devices capable of making and receiving phone calls, including portable/mobile devices and desktop devices, may be used without departing from the scope of the present disclosure. The payer device 402 and the payee device 422 may be implemented using any appropriate combination of hardware and/or software configured for voice communication over the voice call network 490 and for data communication over the data network 480. For some embodiments, there may be no need for the payee device 422 to be capable of data communication over the data network 480.

The payer device 402, the payee device 422, and the PSP server 470 may each include one or more processors, memories, and other appropriate components for executing instructions such as program code and/or data stored on one or more computer readable mediums to implement the various applications, data, and steps described herein. For example, such instructions may be stored in one or more computer readable mediums such as memories or data storage devices external to the devices and/or accessible over the data network 480.

When the payer device 402 and the payee device 422 are connected in a phone call, the in-call payment app, discussed above in connection with FIG. 1 above, presents a dial pad or an in-call screen on the display 404, 424. The display 404 of the payer device 402 in FIG. 4A shows an example of a dial pad comprising a caller/callee ID 408 (e.g., the dialed/incoming phone number and the associated name if found in an address book), a payment button 410, a plurality of buttons 412 for other phone functions, and an end call button 414. The display 424 of the payee device 422 shows an example of an in-call screen similarly comprising caller/callee ID 428, a payment button 430, a plurality of buttons 432 for other phone functions, and an end call button 434. Note that a user can alternate between a dial pad or an in-call screen when desired. Note also that a variety of configurations for a custom dial pad or an in-call screen may be used without departing from the scope of the present disclosure.

After verbally negotiating a purchase and/or payment, if desired, the payer can tap on the payment button 410 to activate a payment handler. As discussed above, in other embodiments, one of the plurality of programmable buttons 406 may function as the payment button, or other means of giving command, such as a voice command, may be used to activate a payment handler.

FIG. 4B shows an exemplary screen display on the payer device 402 after the payment handler has been activated. The payment handler presents on the display 404 a prompt window 440 comprising payee information 442, an input box 444 for a payment amount, a confirmation button 446, and a cancel button 448. In this example, the payee's user ID, which is shown in the payee information 442, is automatically retrieved without the payer's input as described above with reference to step 108. Thus, the payer needs only to enter a payment amount in the input box 444 using a virtual keyboard or any other input method natively provided by the operating system of the payer device, and then tap on the confirmation button 446 to send a payment request to the PSP server 470 over the data network 480.

FIG. 4C shows exemplary screen displays on the payer device 402 and the payee device 422 after the PSP server 470 has processed the payment request. In this example, notification of payment is sent out to both the payer and the payee over the data network 480. The in-call payment app on the payer device 402 receives the notification, which may be presented on the display 404 as a popup message 452 containing information regarding the payee and the payment amount. Similarly, the notification may be received by the in-call payment app on the payee device 422, and presented on the display 424 as a popup message 462 containing information regarding the payer and the amount received. In other embodiments, the notification message may be presented on the payee device 422 as a push notification message, an SMS text message, an email, and/or a voice alert, even if the in-call payment is not running.

Referring now to FIGS. 5A to 5D, an exemplary system of facilitating an electronic payment transaction while a smart mobile phone and a landline phone are connected in a phone call is illustrated. FIGS. 5A to 5D also show exemplary screen displays with which the payer and the payee may interact while a payee-initiated electronic payment transaction is being processed according to one embodiment. In this example, the payer device 502 is a mobile phone as described in connection with FIG. 4A above, while the payee device 522 is a landline phone capable of generating a DTMF signal or any other type of in-band signal suitable for transmitting information regarding a payment and for activating a payment handler on the payer device 502. In addition to a conventional numeric keypad 540 for dialing, the payee device 522 may have a display 524, a payment request button 526, a confirmation button 528, and a cancel button 530, which allow the payee to initiate an electronic payment transaction and enter information regarding the payment (i.e., the payee's user ID and a requested amount). In other examples, the in-band signaling and input/output capabilities may be provided by an add-in module that is placed between a conventional landline phone and a phone line to the voice call network 490.

The payee can press the payment request button 526 as shown in FIG. 5A to initiate an electronic payment transaction during a phone call with a payer. A prompt 532 asking the payee to enter a requested amount is then presented on the display 524 on the payer device 522, as shown in FIG. 5B. As discussed above in connection with step 206, the payee may only need to enter the payee's own user ID once when the payee device 522 is first initialized, not every time when the payee initiates an electronic payment transaction. After the payee enters and confirms the requested amount using the keypad 540 and the confirmation button 528, the payee device 522 transmits to the payer device 502 over the voice call network 490 an in-band signal carrying the payment information (e.g., the payee's user ID and the requested amount) and a command to activate a payment handler. When the in-band signal is transmitted, the payee device 522 may also present a message 534 containing the requested amount and information regarding the payer (i.e., the payer's phone number retrieved from a caller/callee ID and the corresponding user ID retrieved from an address book if available) on the display 524, as shown in FIG. 5C.

FIG. 5C also shows an exemplary screen display on the payer device 502 when the payment handler is activated in response to the in-band signal transmitted by the payee device 522. The payer device 502 may present on the display 504 a payment request prompt 510 containing the payment information (e.g., the payee's user ID and the requested amount) transmitted by the payee device 522. The payer can approve the payment by tapping on a confirmation button 512 presented in the prompt 510, after which the payer device 502 transmits a payment request over the data network 480 to a PSP server 470 for payment processing.

FIG. 5D shows the payer device 502 and the payee device 522 after the PSP server 470 has processed the payment request and transmitted notifications to both the payer and the payee. In this example, the payee has opted to receive a notification via an automated phone call. The PSP server 470 instantly calls the payee at the phone number associated with the payee's account, and the payee may pick up and listen to the incoming automated notification call through a call waiting service available from most landline phone operators. The payee may then return to the call with the payer, and acknowledge receipt of payment to complete the transaction. In another example, a voice alert may be injected into the voice call audio stream so that the payee can hear the notification while on the line. In yet another example, the notification may be transmitted to the payee device using DTMF signaling or any other type of in-band signaling. FIG. 5D also shows the payer being presented with a pop-up message 514 when the payer device 502 receives the notification over the data network 480.

These communication apps may also receive a notification transmitted by a PSP in addition to, or in place of, the in-call payment app 604 or the payment handler 608. User device 602 also includes one or more device IDs 620 which may be implemented, for example, as operating system registry entries, cookies associated with the browser application, identifiers associated with the hardware of user device 602, or other appropriate identifiers, such as a phone number. In some embodiments, the user identifier may be used by a payment service provider to associate the owner of the user device 602 with a particular account as described in connection with step 116 in FIG. 1 .

A PSP server 622 may have one or more payment applications 628, which may be configured to interact with the user device 602 over a data network 480 to facilitate electronic transfer of money between users of a PSP. In this regard, the one or more payment applications 628 may provide an API (such as PayPal API by PayPal, Inc.) through which the user device 602 can interact. The PSP server 622 may also maintain a plurality of user accounts 624, each of which may include account information 626 associated with individual users. For example, the account information 626 may include private financial information of users such as account numbers, passwords, credit card information, bank information, bank information, or other financial information which may be used to facilitate electronic transfer of money, as well as device information from a user device that aids in determining an appropriate account to access.

The PSP server 622 may also have a notification generator 630 suitable for generating notifications that may be received by the user device 602 during a phone call. The notification generator 630 may transmit a notification using an automated voice alert, an SMS text, a push notification message, an email, or other suitable means. The notification generator 630 may also communicate with the in-call payment app 604 or the payment handler 608 in the user device 602 to deliver a notification.
